Abstract: On a die that has etchings on a surface, firstly a sheet of negative photoresist is laid down which, by means of an exposure and subsequent development, is left only above the etchings; then, upon the negative photoresist, a positive photoresist is applied, which is subjected to exposure and development to produce functional geometries deposited in thin film; subsequently the positive photoresist is removed in a “lift-off” operation, and the negative photoresist is taken off in a plasma operation, thus revealing the etchings.

Abstract: This invention relates to a printhead in which a plurality of resistors are selectively activated by an external control circuit to produce the ejection of droplets of ink through nozzles located in correspondence with the resistors. Selection and activation are performed according to a matrix having a plurality of vertical lines corresponding to the number of resistors per group of nozzles and a plurality of horizontal lines corresponding to the number of groups of nozzles in the head. The groups of nozzles in the polychromatic head comprise real nozzles and fictitious nozzles, as a result of which the groups of nozzles have a regular layout, and are uniformly distributed and equivalent to the corresponding layout of a monochromatic head. With this solution, polychromatic heads having the same number and the same disposition of contacts with the external circuit and the same height as a monochromatic head can be manufactured simply.
